To all whom it may concern:

`Be it known that I, JOHN MCGRANIGHAN, residing at Roxboro, in thek county of Philadelphia and4 State of Pennsylvania. have invented certain Improvements in Railway-Ties, of which the following isa specification.

This invention relates to the'use of concrete or artificial-stone blocks for supporting railway-rails; and its leading object is to so construct and stay such blocks as to provide the maximum strength and endurance at the minimum cost.

The improvements provide a greater facility for manufacturev and handling and greater economy inuse not only by reason of the increased strength and durability, but because the parts are separable and can be renewed without diliculty.

. In the accompanying drawings, Figure l represents a plan view of a block and connec- .tions made 1n accordance wlth my invention.

Fig. 2 represents an end view of the same. Fig. 3 represents a side elevation and sectional view of blocks joined together in operative relation as a tie, and Fig. 4 represents a view of a hook-bolt used in the invention.

As shown inL the drawings, the tie comf prises the concrete or artical-stone blocks 1,

of rectangular vertical longitudinal section and symmetrical trapezoidal vertical transverse section, having the metallic binders or bent rods 2 therein, the several binders being preferably disposed in parallel planes at regular intervals between the top and `bottom of each block.

An exterior band 3 extends longitudinally of the top and bottom and vertically across the outer end of each block. Each band has lel upper and lower members of the bands,

providing vertical struts for taking strain from the rails. .Bolts 6 are passed through the tubes 5 and engage the clips 7, which clamp the rails 8 to the bands and blocks. Bolts 9 clamp together the upper and lower members of the bands at the inner edges of the blocks, hooks 9 on the bolts engaging the extensions 3" of the bands. The bands of the respective pairs of blocks have their members 3l overlapped and connected together by bolt 10, whereby the whole is formed into a tie which when placed is surrounded by ballast in the usual manner, the ballast being filled between the blocks and against the battered sides thereof; This-construction provides a metal framework or skeleton so combined with an artificial-stone block as to be readily applied to or removed therefrom in the main features, providing great strength and endurance at a comparatively low cost. I am aware that it is old to produce a tie of concrete combined with metal strengthening members arranged in various ways, and I am thoroughly familiar with the qualities of the more practical construction of this class that have been proposed; but I have been unable to find in any of the proposed constructions for such ties a product that at all approaches the present improvements in strength, durability, economy, and convenience.

Having described my invention, I claiml. A railway-tie comprising a block, a band embracing said block exterior thereto, a bolt passing through said block and band, in combination with a rail and a clamp engaged by said bolt to said rail.

2. A railway-tie comprising a block, a band embracing'said block exteriorthereto, tubes disposed in said block between members of said band, bolts passing through said tubes and bandvmembers, and rail-clamps engaged by said bolts. l

3. A railway -tie comprising a pair of blocks, and an exterior band embracing the top, bottom and outer end of each of said blocks, said bands having extensions that are secured` together.

4:. A railway-tie comprising a pair of blocks and a band clamped to the exterior of each block, said bands having respectively twists therein disposed so as to make contact 'with said blocks and connected extensions having IOO and battered sides, in combination with a my hand, this 24th day of June, 1905, in the band disposed longitudinally on the exterior presence of the subscribing Witnesses.

of said block, said band having a twist there- JOHN M CGR ANIGH AN 5 hook-bolt engaging members of said band togeth er.

' In testimony whereof I have hereunto set in adjacent to the edge of said block, and a Witnesses:
